Wow, I sounds like you guys have put a lot more thought it to this than
I did.
Currently I am a memeber of a club. I totally understand that a club,
set to break even and with many volunter hours is much cheaper than a
business that actually has to pay people let a lone make a profit.

(my club was $1500 to buy in C172 aprox $65 hour with current fuel
prices)

I started thinking and I guess sport pilot planes aren't going to be
any cheaper than a C152. The difference in fuel burn just dosen't
make up for the fact that a new airplane means more debt / interest
and insurance costs. I have yet to be proven that a rotex or jabiru is
much cheaper to operate than a Lyc.

I am still will to rent one from time to time if anyone ever decides to
rent out one in the Seattle area. (feel free to email me if you know
where a rental is)

I still hope the sport pilots rule encourages for pilots. Of course
how can anyone get a license in only 20 hours but that's another story.
